How do i verify my dts modification with faster way(not bitbake whole image always)

[Jordan_Lin]

Hi ST:

I am devloping the STM32MP131c  with yocto package

Everytime after i modify the dts using devtool, i need to

bitbake st-image-core

and flash all image with stm32cubeprogramming tool

 

There is a ethernet on my board

Is there any faster way to help me verify my dts modification

Maybe compile the dtb only and scp into DUT 

or compile bootfs only and i can only flash the bootfs partition

 

Thank you

Hello @Jordan_Lin ,
Yes, you can use what we call the Developer Package (with SDK) to just cross compile the SW component you want to test, or here in this situation, just compile your device tree modified.

The wiki article is here: https://wiki.st.com/stm32mpu/wiki/STM32MPU_Developer_Package

Then, as you said, a device tree modification is simple to test as you can just replace the existing one in the bootfs partition of your flash memory.

Kind regards,
Erwan.
